The iOS 13.2 Developer Preview, which was originally scheduled to be pushed yesterday, did not arrive as scheduled, but was postponed until the early hours of the morning. Although the time has been postponed, this update has brought a lot of surprises to the iPhone 11 series users, because Deep Fusion is coming.
What is Deep Fusion?
This is called “The Crazy Philosophy of Computing Photography” by Apple Senior Vice President Phil Schiller. It can take 8 photos before the user presses the shutter and combines a long exposure image when the shutter is pressed. Create a high dynamic range photo that is comparable to a professional camera, giving you more detail even in low to medium light conditions.
Deep Fusion This year’s three new iPhone exclusive features did not come with the launch of the new iPhone. But after nearly a month of waiting, it finally came.
Not much nonsense, let’s see how it works.
Everyone knows that in the past models, Apple has used Smart HDR to help users take high dynamic range photos. Naturally, Apple users are most concerned about, and believe that there is a difference between Deep Fusion and the former.

From the proofs, I can see that after opening Deep Fusion, the proofs will have more detailed details.
The other set of proofs is from foreign technology blogger Chuck Skoda, who directly zoomed in on the proofs and compared the performance. (Smart HDR on the left and Deep Fusion on the right)
In fact, the new iPhone’s breakthrough in photography is mainly due to the more powerful A13 biochip. Compared with the previous generation, this chip can increase CPU speed by up to 20%, energy consumption by up to 30%, and four energy efficiency core speeds by 20% and energy consumption by 40%.
In addition, A13 Bionics has added two new machine learning accelerators that can perform matrix math operations up to 6 times faster and can perform 1 trillion operations per second.
More powerful computing power to ensure the implementation of Deep Fusion.
Under Smart HDR, the synthesis of Deep Fusion does not need to go through the ISP. Instead, when it takes more photo data, they will be directly sent to the neural network engine. The neural network engine has a brand new model. Can integrate a large number of photos – it will compare the 24 million pixels pixel by pixel to synthesize the final photo.
There are also some details of the experience beyond the imaging effects.
Continue Apple’s consistent concept of making shooting as easy as possible, and Deep Fusion does not have a switch. The system automatically determines if you need to turn on Deep Fusion based on the shooting environment. Previously, Schiller also revealed that DeepFusion will only be activated under illumination at 10-600 lux. If the light is below 10 lux, the camera is enabled in night mode.
Foreign Media The Verge further discovered that the three different lenses on the new iPhone actually have different conditions for turning on Deep Fusion.
Firstly, the wide-angle lens will enable Smart HDR in a bright to medium-light environment, Deep Fusion will be enabled in medium to dark environments, and Night Mode will be enabled in almost dark environments. So Schiller’s above mentioned 10 lux and 600 lux as the enabling logic for the dividing line, it should be when using the wide-angle lens.
Second, when using a telephoto lens, Smart HDR will only be enabled in a very bright environment, and the rest will only use Deep Fusion.
And finally because the Super Wide Angle lens does not support Deep Fusion and Night Mode, only Smart HDR will be enabled for this shot.
Accepting usInterview, when asked about the time it takes for Deep Fusion to compose a photo, Schiller said it only takes one second.
It’s really fast, but it can still be felt in this second. According to the forum, users have already experienced the experience of Deep Fusion. After taking the photo, enter the photo album and find the photo you just took. You will find that the photo will “shake” and then re-display a photo that is obviously different from the original.
More photo information means that this photo needs more space for you. The Smart HDR photo size on the iPhone XR is 1.4MB, and the Deep Fusion size on the iPhone 11 is further increased to 2.4MB.
So users who are buying the new iPhone with the Deep Fusion feature need to think about capacity issues.
